To aZZ whom it may concern.-

Be it known that we, EVAN TV. CORNELL and FREDERICK H. KNAPP, citizens of the United States, residing at Adrian, in the county of Lcnawee and State of Michigan, have invented certain new and useful Improvements in Attachments for Labeling-Machines; and we do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and' practice the same.

This invention relates to certain new and useful improvements in can-labelin g machinery, as will be hereinafter more fully set forth in the drawings, described, and pointed out in the specification.

Our invention refers more especially to an improved spacing mechanism for the conveying of the cans over or through the machine, whereby the cans are maintained an equal distance apart, so as to prevent the crowding thereof upon one another and to provide against the cans following each other too closely over the labels, and to the arrangement of the conveyer-belt whereby the removal of the paste from the cans is obviated.

In order to more thoroughly understand our invention, reference must be had to the accompanying sheet of drawings, wherein- Figure I is a view in side elevation of our attachment, showing same connected to the frame of a labeling-machine. Fig. 2 is atop plan view of the mechanism illustrated by Fig. 1. Fig. 3is an end elevation of the mechanism set forth in Fig. 2, viewed in the direction of the arrow; and Fig. at is a cross-sectional elevation taken on line X X, Fig. 2.

The letter A is used to indicate the frame of a labeling-machine, within which are located the paste-holder A, paste applying wheel A and label-holding receptacle A all of which parts will be found set forth in Letters Patent No. 51l,705, granted to Cornell February 13, 1894, and which form no part of the present invention.

Above the frame of the labeling-machine are supported, by brackets or straps B, the longitu dinal side pieces 13 B Through the ends of these side pieces extend the cross-shafts G C. To one end of the shaft 0 is fastened the crank-handle G which constitutes this shaft the drive-shaft. Upon the shaft 0 we rigidly secure the belt-wheels D D D over which travel the endless conveyer-belts E E and drive-belt The drive-belt transmits the motion of wheel D to the wheel F, rigidly secured to shaft C. Upon the shaft we rigidly secure the feed-disks F F which are driven by the rotation of said shaft. We also locate upon this shaft the belt-wheels G G, which are free to rotate thereover independent of the shaft. Motion is imparted to these wheels or rolls by means of the endless conveyer-belt E E, which travels thereover, and inasmuch as the Wheels or rolls G G derive motion direct from the shaft 0, which is rotated at a higher speed than shaft C, inasmuch as its motion is derived from the power transmitted by a small wheel D to a large wheel F, it is obvious that the speed of the said rolls or wheels will be greater than that imparted to the disks F F, which derive motion from shaft 0.

The diameter of the disks F F is greater than that of the rolls or wheels G G. Consequently they extend beyond or below the periphery thereof and serve as feed-disks for the cans, as will be hereinafter more fully set forth.

In order that the paste deposited upon the traveling cans may not be removed by the endless conveyer-beltsavhich it would did the entire width of the belts bear upon the cans, we cause the same to be thrown at an angle thereto, whereby the belts only contact with the flange of the can heads or ends, thus not coming in contact with the body portion proper. For the purpose of throwing the conveyer-belts at an angle orincline we suspend below the side pieces B B of the conveyerframe rolls a, which are held in place by the downwardly-extending straps a. The end of these straps we bend inward at an angle, as shown by Fig. 4, and the rolls a are secured to shaft or axle b. The flange b of the roll a serves as a keeper for the conveyer-belts, the outer edges of which bear upon the flange of the roll. The angle or inclination of these rolls,which we shall call keeper-rolls, serve to maintain the under side or face of the endless conveyer-belts at, an angle to the cans. Consequently the same only engages with the cans at their ends or edges. Consequently the tops of the belts do not lie flat upon the cans. In order, however, to prevent the belts climbing off the keeper-rolls,we journal within the side pieces B B the ends of cross-rolls II. These rolls have cone-shaped grooves h out near the outer ends thereof,within which the endless conveyer-belts travel. By causing the belts to travel within the cone-shaped grooves h we not only release the keeper-rolls of undue strain, but at the same time assist in maintaining the belt at the proper inclination.

The cans are supplied to the labeling-machine by means of the runway II. This runway delivers the eans to the front or feed end of the machine, beneath the disks F F These disks while being rotated bear upon the cans and convey the same to the labelingmachine and beyondthe rolls G G,when they are engaged by the conveyer-belts and carried the entire length of the machine and discharged thereby in the discharge-chute II with the label applied thereto. the conveyenbelt travels with greater speed than the feed-disks it is obvious that after one can has-been fed into the machine it willbe carried quite a distance by the conveyerbelt before the feed-disks can have delivered the next can to such a point as tobe received by the conveyer-belts. Consequently the conveyer-belts maintain the cans an equid-istance apart and prevent the crowding of one upon the other during travel through the machine. This is absolutely necessary, for were'the cans permitted to travel through the machine the same as they do within the runway II they would jam against each other.

Having thus described our invention, what wheels loosely mounted upon said shaft, the

belt-wheels and small drive-wheels rigidly secured to the rear shaft, a drive-belt for transmitting the motion of the small drive-wheel to the large drive-wheel, the endless conveyerbelts for imparting the speed of the fixed belt- Inasmuch as wheels, and of mechanism for imparting mo-- tion to the rear shaft of the conveyer-frame.

2. The combination with a labelingmachine, of the conveyer-belts, mechanism for imparting motion thereto, and of the keeperrolls so arranged as to throw the conveyerbelts at an angle to the traveling cans, whereby the belts engage the cans at the ends thereof.

3. The combination with a labeling-machine, of the conveyer frame supported thereabove, the endless conveyer working therein, and devices arranged at the sides of the path of the cans for causing the endless conveyer to engage the edges of the cans at an angle to the ends.

at. The combination with a labeling-ma chine, the conveyer-frame supported there above, the keeper-rolls suspended therebelow at an angle, the endless conveyer-belts working within the frame, said belts being thrownat an angle-by means of the keeperrolls so a-s to engage the cans at an angle and the rolls secured within the conveyer-frame,

said rolls having the cone-shaped grooves cut therein within which the'conveyer-belts work.

5. In a labeling-machine the combination with the feed-disks, of the conveyer mechanism independent of the disks and of mechanism for imparting greater speed to the conveyer mechanism than to the feed-disks, whereby the cans fed into the machine are automatically spaced while being carried through the machine.

6. In a can-labeling machine, the combination with a track, of a conveyer mechanism comprising endless belts, pulleys over which the belts pass, shafts on which the pulleys are mounted, and feed-disks at the forward EVAN WV. CORNELL. FREDERICK II. KNAPP.
